Trouble in paradise? Vishnu/FFtec N54 335ii Single Turbo kits experiencing issues as a BimmerBoost member runs 12.5@121 with misfires and having to short shift

BimmerBoost would like to thank member GeorgiaTech335Coupe for his openness and honesty regarding his Vishnu/FFTEC single turbo setup. Recently, this member took his single turbo upgraded 6-speed manual 335i to the PBIR (Palm Beach International Raceway) dragstrip in Florida to do some testing. His best run was a 12.50@121.6 alongside a 12.8@117. Yes, these times are quite a ways away from the 10.8@131 glory pass from Vishnu demonstrating the kits capability.

This is in no way the fault of GeorgiaTech335Coupe who experienced misfires on his car and had to short shift at 6300 rpm in order to avoid them. Now, Vishnu has basically portrayed this kit as perfect and ready for sale with nobody having any issues. The reason BimmerBoost is bringing this issue to the attention of the community is for potential buyers to understand what they are getting into.

There is absolutely nothing wrong with having issues when modifying a car to this level and BimmerBoost is confident Vishnu will resolve them. There is something wrong with pretending nothing is wrong. A few cars with the single turbo kits have gone up for sale and apparently a total of three people, that are willing to open their mouths, are having misfire issues with these kits.

These issues will no doubt get resolved but potential buyers and current customers needs to be aware of the process, effort, and that progress is being made. Pretending nothing is wrong and collecting money simply is the wrong way to go about this and once again (it's becoming a trend) BimmerBoost is the only site bringing these issues to the attention of the community.

For the record, a member by the name of @tmo335tt says he has a hardware solution for the misfires that he will likely share with Vishnu (hopefully not for free). Interesting that it isn't Vishnu but the community solving this.

Thanks again to @GeorgiaTech335Coupe for sharing his details, good or bad, as we all learn thanks to honesty and openness. There is more to tuning than just collecting money.

I've said this once and I'll say it again...Misfires aside, this chassis is terrible at power levels above the mid 400's. You get terrible suspension, drivetrain, transmission issues and reliability issues past that level. We will not see a consistent 10 second 335i full street car ever... The fact that Shiv is the only one that has done 10's with essentially a drag setup is further proof... I wish the best of luck to all ST owners.

All of the things you said, you can upgrade, and still be cheaper then a comparable M3

Who is talking about an M3?? M3's and 335i's are not competitors... the right thing to do is buy a completely different car that is built to handle this kind of power. Even if you want to get into the details; a new 335is will run you 55K, another 12 for the ST, and another 5 for the supporting mods... so you wouldn't be far off with an M3 anyways but I don't think an M3 is right for those power levels either.

You might be right, but it's always more fun to make a car fast that isn't supposed to be fast.

The N54 may not be great strip car but it is a fantastic street/highway roll car and that's where i do 100% of my driving and i love it.

Sure but above 130 MPH these cars run out of steam no matter how big your turbo... Shiv's 458 win is the only solid run I have ever seen. Any RB equipped car will get a train ran on it by a bolt on Z06... I guarantee this. Remember that race that was supposed to happen between Shiv and his boys Z06? Yeah...

That's a pretty bold statement which I will try to prove wrong in the not so immediate future.

I don't believe that is the case. Shiv(or anyone else for that matter) just hasn't had the balls to actually put a BIG turbo on an N54. A 6266 isn't exactly a big turbo in my book, i mean just look at the dyno graphs. The turbo is sized well for mid range torque and decent top end but it's definitely not a turbo for huge power.

I wish you the best of luck... I really want to see it. Key to point out is that I mean a C6 Z06 with exhaust, intake, headers and tune but run a stock one just for the hell of it too. Enrita could never outrun one with RB's; he was close but it ran away top end. Pretty funny the Z06 only had an intake.

Me too we'll see though. The funny thing is with the group of cars that I run with a bolton C6 ZO6 would be at the low end of the totem pole...so $#@!, where will I be LOL!

A car that claims to dyno 640 or 650 or whatever should be much faster. He claimed a 3250 lb race weight... s*it that thing should have gone way faster than a bare 130 MPH trap... I am not trying to hate I just don't think the chassis can perform. This is the way I see it; the autos will be inherently slow and the manuals will be too difficult to drive to have consistently strong results.

Once my car is running I can find out.

My brother has a stock C6 Z06 and a friend of mine has a C6 Z06 with Cam, headers, intake, I believe.
